Recent studies have pointed out that the incidence of primary glomerular diseases is similar in the elderly and in younger populations. However the clinical characteristics of the different subtypes may be different in the advanced age. Minimal change nephropathy responds favorably to corticosteroids and/or cyclophosphamide, but many untreated or non-responder patients progress to end-stage renal disease or die from nephrotic complications. Focal and segmental glomerulosclerosis also has a severe prognosis in older patients but some 50% of patients may attain remission of the nephrotic syndrome with a prolonged corticosteroid treatment. The responders tend to maintain normal renal function over time. Membranoproliferative glomerulonephritis and IgA nephritis have a severe prognosis and do not respond to treatment. The clinical presentation and the outcome of membranous nephropathy are similar in the elderly and in younger adults. Corticosteroids are of little benefit while a 6-month treatment with chlorambucil and methylprednisolone may obtain remission of the nephrotic syndrome in about 2/3 of older patients. Crescentic glomerulonephritis has an ominous prognosis in older patients but some patients may improve if treatment with methylprednisolone pulses is started early. Acute postinfectious glomerulonephritis is often associated with renal failure in older patients. The prognosis may be severe.
